ATTORNEY Patented May 23, 1933 UETEZD STATES ROBERT HOE, OF HYDE PARK, NEW YORK HOUSEHOLD POWER UNIT Application filed October 31, 1930. Serial No. 492,401.

This invention relates to a novel and improved houshold power unit, and more particularly to an arrangement whereby a container may be effectively supported on an operating head.

In the prior art, it has been customary to support the container separately from the head which carries the heater or other utensil used to operate on food in the container. For the purposes of simplicity, I shall hereinafter refer to this utensil as a beater, although by the use of that term I do not intend to limit myself.

By my invention, I avoid many of the difliculties and inefliciencies attendant on the above arrangement, and the manner in which I do this will be best understood from the following description and the annexed drawings, in which:

Fig. 1 is a vertical view, partly in elevation and partly in section, showing the invention as applied to a household power unit;

Fig. 2 is a plan view of the arrangement appearing in Fig. 1;

Fig. 8 is a view on an enlarged scale showing the opposite side of the head from that appearing in Fig. 1, parts being broken away and parts shown in section for the greatest simplicity Fig. 4 is a view taken from the right of Fig. 3.

Referring first to Figs. 1 and 2, I have shown my invention as employed with a type of household power unit, such as is more fully illustrated and claimed in my copending application, Serial No. 418,109. The invention finds particular use with thistype of unit, although it may be used with others.

The unit shown comprises a plurality of legs 1 carrying a base plate 2 upon which is supported a motor 3 which, through its shaft 4, operates a train of gearing in a gear case 5. The gearing in the case 5 transmits power to two outlets 6 and 7, the details of these outlets not being shown, as they are not necessary to an understanding of the invention herein. It is sufficient to say that these outlets may be in the form of clutches which are adapted to operate shafts on devices such as that illustrated in the drawings. Such devices may be supported on hinge pins 8, and may be held in operative position by means of latches 9. Each device is provided with a driven shaft 10, and this shaft when the dev1ce is in operative position, is clutched to one of the power outlets 6 or 7 In the illustrated embodiment, the device is shown as one intended to operate a beater, and this device is generally known as a beater head. For the sake of simplicity, it will hereinafter be referred to as a head 11, al though by that term I intend to embrace any device which may be operated from the gear case. The head is shown as supported on a bracket 12 which, in turn, is supported on two of the three hinge pins 8 in the manner more fully described in my aforesaid copending application. The head has disposed thereina planetary gearing of any suitable type, the details of which it is not considered necessary to illustrate, it being suhicient to say that the gearing results in a bodily movement of a vertical shaft 13 about the vertical axis represented by the line 14, and at the same time causes a rotation of the shaft 13 on its own axis. The gear arrangements providing such planetary movements are well known in the art.

Theshaft-18 has secured thereon a heater 15 whereby, when the shaft is given its planetary movement, the food in the container 16 will be beaten or otherwise agitated, depending upon the type of the beater.

The container is provided with the usual beaded rim 17 and may or may not have a handle 18. The rim is received in horizontally opening grooves 19 which form hooks arranged in downwardly extending ears 20 on the head. These ears are shown as disposed on the side of the head next the gear case, and are disposed generally on one side of the container. On the opposite side of the container, and substantially diametrically across the container from a point half way 7 between the ears 20, is arranged a latch 21,

this latch being mounted on a pivot 22 extending between a pair of parallel cars 23. These ears 23 depend from the head, but differ from the cars 20 in that they have their lower edges forked as indicated, the forks being so arby the latch.

ranged as to form downwardly opening recesses to receive the rim 17 of the container.

The latch is provided with a hook end 24 adapted to engage under the rim 17 and hold it in the recesses in the ears 23. The other end of the latch is formed as a finger piece 25, whereby the latch may be operated, and the latch is normally held in the position shown in Fig. 1 by means of a coil spring 26 having one end held against an abutment 27 on one of the ears 2?), and the other engaging the latch to rotate it on its pivot. Movement, of the latch by the spring is limited by engagement of the latch with a stop 28, which may be in the form of a bar extending between the ears 23.

The hook 2a is provided with a cam surface 29 whereby, when the rim 17 is raised, it will engage the surface 29 and force the latch outwardly to some such position as shown in Fig. 3 so as to permit the rim to enter the recesses in the forked ends of the ears 23.

By the above arrangement, when it is de sired to support a container in position to cooperate with a beater, all that is necessary is to insert the rim in the grooves 19 which will automatically correctly place the container, so far as this part of the rim is concerned. and will serve to help in centering it with respect to the beater. The part of the rim substantially opposite the ears 20 is then raised until it engages in the recesses or grooves in the ears 23, when it will be locked in position It will be noted that the suspension is substantially a three-point one, which will positively and accurately center the entire container so that the beater will be properly placed in the container at all times.

\Vhen the container is thus secured to the head, th operation may be described as one in which the container rim is engaged by a portion of the head and then rocked into position where it engages another portion and is there locked. hen the container is removed from the head, the operation described above is, of course, reversed. The container may be quickly put in place and removed, and this may be done by placing it on the head while the head is in position on the hinge, or by first securing the container to the head and then placing the head and container together on the hinge. Similarly, the container may be removed from the head without disturbing the head, or may be removed from the power unit with the head.

The action of the'latch, when it engages the rim is to not only hold the rim upwardly, but also to force it horizontally into engagement with the sides of the recesses and thus serve to bind the rim;

I/Vhile I have shown the invention as embodied in a specific form, it is to be understood that various changes in details may be made without departing from the scope of the invention, and I therefore do not intend to limit myself except by the appended claims.

This application forms a continuation in part of matter difierent from my copending application, Serial No. 310,840.
